BACKGROUND

Managing a patient's blood glucose levels can be challenging. Generally,a patient must provide a blood sample to a meter multiple times each dayand must self-assess based on the blood glucose measurements andassociated trends, along with other factors he/she thinks may beinfluencing the measurements. The patient typically provides the bloodsample by lancing his/her finger (or other body part) with a lancingdevice, applying the blood sample to a separate test strip, andintroducing the test strip to the meter—three separate components arerequired. This arrangement often means patients are less likely to testtheir blood glucose levels as often as recommended and that anyconclusions drawn from the measurement are based on incompleteinformation. Moreover, it can be difficult to provide relevant bloodglucose information to others for whom accessing such information may bebeneficial.

SUMMARY

In general, this disclosure is directed to a biological property testingapparatus. Some exemplary embodiments of the biological property testingapparatus can include a testing module. The testing module can include abase comprising a primary surface extending in a base plane, a lancetstation supported by the base and having a lancet, and a test section.The test section can have a test strip channel.

In certain embodiments, the test strip channel can have a main channelportion extending generally parallel with the base plane, and an angledchannel portion that forms an angle with the main channel portionbetween 5 degrees and 90 degrees. The test strip channel can house abiological test strip oriented so that a meter connecting end of thebiological test strip is adjacent to the main channel portion and asample end of the biological test strip is adjacent to the angledchannel portion.

According to some embodiments, the test section includes a samplecavity. The biological property testing device can have a cover tabcoupled to the base and movable from a covered position to an uncoveredposition. A moisture barrier can seal off the sample cavity when thecover tab is in the covered position and not seal off the sample cavitywhen the cover tab is in the uncovered position. A sterile barrier canseal off the lancet aperture when the cover tab is in the coveredposition and not seal off the lancet aperture when the cover tab is inthe uncovered position.

The biological property testing apparatus according to illustrativeembodiments can have a meter module removably attachable to its housing.The meter module can receive the meter connecting end of the biologicaltest strip when the testing module and the meter module are attached tothe housing.

Some embodiments provide a housing that facilitates use of conventionalbiological test strips in new biological property testing devices andapparatuses. One or more conventional biological test strips can beassembled into a base that also includes a corresponding number oflancet stations. The sample ends of the biological test strips can bepositioned proximate to the lancets of the lancet stations to minimizethe distance a patient must move his/her lanced finger or other bodypart. The biological test strips can be bent so that the sample ends arepositioned to easily receive a biological sample from the patient. Themeter connecting ends of the biological test strips can extend out ofthe housing and into a meter module that includes electronics formeasuring a biological property of the biological sample provided by thepatient.

In some embodiments, prior to use, the testing module keeps the lancetin the lancet station sterile and keeps the biological test stripgenerally free from moisture. A sealant can be applied to preventmoisture from entering a sample cavity of the testing module through theend of the testing module through which the meter connecting end of thebiological test strip extends. The testing module can include a covertab that prevents moisture from contacting the biological test strip andkeeps the lancet sterile prior to use. In many embodiments, a moisturebarrier is provided on an underside of the cover tab to prevent moisturefrom contacting the biological test strip prior to use. In someembodiments, a desiccant can be included proximate to the sample end ofthe biological test strip prior to use. In many embodiments, a sterilebarrier is provided on an underside of the cover tab to keep the lancetsterile prior to use.

DETAILED DESCRIPTION

FIGS. 1-8C illustrate various components of embodiments of a biologicalproperty testing apparatus 200 according to an embodiment of the presentdisclosure. Referring to FIGS. 1 and 2 , a biological property testingapparatus 200 is illustrated. The biological property testing apparatus200 comprises a cover 202. In FIG. 1 , the cover 202 is illustrated in aclosed position, and in FIG. 2 , the cover 202 is slid to an uncoveredposition to illustrate internal details of the biological testingapparatus. The cover 202 can have a generally planar surface 204 toenclose components of the biological testing apparatus 200.

Referring again to FIG. 1 , exemplary embodiments of the biologicalproperty testing apparatus 200 can be generally rectangular and of acompact size to promote portability. In some exemplary embodiments, thebiological property testing apparatus 200 can have overall dimensions tocorrespondingly attach to a mobile device, such as a smartphone. Forinstance, the biological property testing apparatus 200 can have anoverall width 208 between about 100 millimeters and about 180millimeters, and an overall depth 210 between about 60 millimeters andabout 90 millimeters. Such embodiments provide a compact constructionand portability to facilitate biological property testing at locationsand times convenient to the patient.

Referring now to FIG. 2 , the biological property testing apparatus 200is illustrated with its cover 202 removed. A housing 212 that can housevarious components of the biological property testing apparatus 200 isshown. The housing 212 can be shaped and oriented to seat a testingmodule 220. As is apparent, in some example constructions, the testingmodule 220 can be removably connected to the housing 212. While FIG. 2illustrates the testing module 220 connected to the housing 212, FIG. 3illustrates the testing module 220 removed from the housing 212. Forinstance, the testing module 220 can be removed by releasing it from thehousing 212. Alternatively, the testing module 220 can be slid or liftedfrom the housing 212. As will be described in further detail below, suchembodiments may permit a user to store one or more biological teststrips in the testing module 220. When the testing module 220 has beenused (discussed elsewhere herein), it can be removed and disposed of andreplaced with a new testing module.

Referring now to FIG. 4 , the testing module 220 can have a base 221 forsupporting one or more lancet stations. The base 221 comprises a primarysurface 223 extending in a base plane “B”. In the example illustrated inFIG. 4 , the primary surface 223 can be the top surface, and the baseplane “B” can be a plane shown in dotted lines in FIG. 4 that includesthe top surface. In certain embodiments, the biological testing devicecan be positioned on a support surface such as a table top (not shown).In such cases, the base plane can be a horizontal plane parallel to thesupport surface on which the biological testing device is placed.

As mentioned above, the biological property testing apparatus 200comprises a plurality of lancet stations supported by the base 221. Inthe exemplary embodiment of FIGS. 4 and 5 , a first lancet station 222A,a second lancet station 222B, and a third lancet station 222C areillustrated. Each of the lancet stations 222A, 222B, and 222C includes alancet. For example, referring to the cross-sectional view of FIG. 6 , arepresentative lancet station 222 is illustrated, and includes a lancet224. The lancet 224 can be supported by the lancet station 222 such thatit is generally stationary relative to a user's finger, thumb or anotherportion of the body during lancing.

Each lancet station 222 comprises a lancet station housing 225 recessedfrom the primary surface 223 of the base 221. The lancet 224 can besupported by the lancet station housing 225. The lancet stations 222 canfacilitate generation of biological samples. For instance, the lancetstations 222 can facilitate lancing a user's finger or other body partso as to generate blood so as to measure a biological propertytherefrom. As will be described further below, one or more test stripchannels 226 that may house a biological test strip 228 to measure abiological property from the biological sample generated at the lancetstation 222. Lancing is discussed in greater detail elsewhere herein.

Continuing with the example embodiment illustrated in FIG. 6 , eachlancet station 222 includes a lancet cover 227 that is movable betweenan un-depressed position (shown in solid lines) in which the lancetcover 227 covers the lancet 224 and a depressed position (shown indotted lines) in which the lancet 224 protrudes through an aperture inthe lancet cover 227. In this example, to generate a biological sample,the user would bring their finger, thumb, or another portion of theirbody toward the lancet cover 227 and apply pressure thereon to move thelancet cover 227 from the un-depressed position to the depressedposition. As the lancet cover 227 moves from the un-depressed positionto the depressed position, the user's finger, thumb or another portionof the body moves toward the lancet 224, and can be lanced to generatethe biological sample. In some embodiments, the lancet cover 227 mayreturn from its depressed position to the un-depressed position when theuser stops applying pressure on the lancet cover 227. Advantageously,such embodiments allow a user to apply a suitable magnitude of pressureon the lancet cover 227 to generate a sufficient quantity of sample,while minimizing pain that may otherwise occur if excessive pressure isapplied while lancing.

As shown in FIG. 6 , according to some exemplary embodiment, the testingmodule 220 can have a test section 244. In such cases, components of thetesting module 220 that are associated with sample generation may bepositioned outside of the test section 244, and components of thetesting module 220 that are associated with biological propertymeasurement can be part of the test section 244. For instance, referringto FIGS. 5 and 8C, the first test section 244A can include the samplecavity 242A, the first test strip channel 226A having a biological teststrip 228. The testing module 220 includes a second test section 244B,having a second sample cavity 242B, and second test strip channel 226Band a third test section 244C, having a third sample cavity 242C andthird test strip channel 226C.

While the biological test strip 228 is illustrated as a separatecomponent housed in the test strip channel 226 in FIG. 6 , it should beunderstood that embodiments whereby components of a biological teststrip 228, such as chemicals that respond to certain chemicals in abiological sample may be provided integral with the base 221. Forinstance, the test strip channel can be coated or provided withchemicals present in commercially-available test strips. In such cases,once a user generates a biological sample (e.g., by lancing at a lancetstation 222), the sample may be collected by a sample cavity 242, andsent to the test strip channel 226 due to the shape and orientationthereof. In such cases, the biological sample may interact (e.g., coator wet) the biological test strip 228 or the chemicals (e.g., reactiveenzymes) provided in the test strip channels 226, to measure a propertychange.

In one example, the biological property measured by the biologicalproperty testing apparatus 200 can be blood glucose in mg/dL. In thisexample, the biological sample can be generated by lancing a user'sfinger or thumb at the lancet station 222. The test strip channel 226can contain chemicals (e.g., glucose oxidase and/or other components)that may react with glucose in the biological sample. Alternatively, agenerally flexible biological test strip 228 can be provided which mayinclude a small spot impregnated with glucose oxidase and/or othercomponents.

Each test strip channel can be aligned with a corresponding lancetstation. For instance, the first lancet station 222A can be aligned withthe first test strip channel 226A, the second lancet station 222B can bealigned with the second test strip channel 226B, and the third lancetstation 222C can be aligned with the third test strip channel 226C.Appreciably, the adjacent positioning of lancet stations 222 and teststrip channels 226 provides a compact construction of the testing module220. For instance, a user may be able to measure a biological propertyshortly after lancing due to the proximity of the lancet station 222 andthe test strip channels 226. Further, such embodiments offer ease ofaccess to biological test strips stored in the test strip channels. Suchembodiments can aid in keeping track of which lancet stations and testsections have been used and which have not. It should be understoodthat, while three sets of lancet stations and test sections areillustrated, any suitable number of sets of lancet stations and testsections (e.g., one, two, four, five, etc.) can be implemented inbiological property testing device embodiments.

FIG. 7 shows an illustrative biological property testing device carrier231, which is a testing module without lancet stations or biologicaltest strips. The biological property testing device carrier 231 caninclude a base 221 with a primary surface 223. The biological propertytesting device carrier 231 can include one or more lancet station sites233A, 233B, 233C, each of which may be configured to support a lancetstation that includes a lancet. The biological property testing devicecarrier 231 can include one or more test strip channels 226A, 226B,226C. Each test strip channel 226A, 226B, 226C may include a mainchannel portion (246 in FIG. 6 ) and an angled channel portion (248 inFIG. 6 ), with the main channel portion and the angled channel portionforming an angle relative to one another. Each test strip channel may beconfigured to house a biological test strip oriented so that a meterconnecting end of the biological test strip is proximate to the mainchannel portion and a sample end of the biological test strip isproximate to the angled channel portion. As shown, the illustrativebiological property testing device carrier 231 includes three lancetstation sites 233A, 233B, 233C and three test strip channels 226A, 226B,226C, with the first lancet station site 233A being aligned with thefirst test strip channel 226A, the second lancet station site 233Baligned with the second test strip channel 226B, and the third lancetstation site 233C aligned with the third test strip channel 226C. Whenthe biological property testing device carrier 231 is assembled into atesting module, a lancet station can be inserted into each lancetstation site 233A, 233B, 233C, and a biological test strip can beinserted into each test strip channel 226A, 226B, 226C.

FIGS. 8A and 8B show a an illustrative biological property testingdevice carrier 231 with three test strip channels 226A, 226B, 226C. Asshown, each test strip channel 226A, 226B, 226C has a main channelportion 246A, 246B, 246C, an angled channel portion 248A, 248B, 248C,and a sample cavity 242A, 242B, 242C. The test strip channels 226A,226B, 226C are assembled in FIG. 8A and disassembled in FIG. 8B. Each ofthe main channel portions 246A, 246B, 246C can be made up of four walls235 (illustrated in connection with main channel portion 246A). In someembodiments, walls 235A, 235B, 235C can define a rectangular crosssection. It should be understood that test strip channels can have avariety of cross sections, such as trapezoidal, elliptical, and so on.As disassembled in FIG. 8B, a removable portion 237A, 237B, 237C isremoved from each of the test strip channels 226A, 226B, 226C. At leastone of the walls 235A, 235B, 235C that form the test strip channels226A, 226B, 226C can be integral with the base 221. At least one of thewalls 235A, 235B, 235C that form the test strip channels 226A, 226B,226C can be removable from the base 221. In some embodiments, when atest strip channel is disassembled, positioning a biological test stripin the test strip channel can be significantly easier.

Referring back to FIG. 6 , the test strip channels 226 are positionedand oriented to permit ease of access to the biological test strip 228.In some examples, each biological test strip 228 can have a sample end230 positioned proximate to the lancet station 222 whereby a biologicalsample is generated. Further, each biological test strip 228 has a meterconnecting end 232 proximate to a meter module 270. Each test stripchannel 226 can be configured to orient the sample end 230 at an angle234 of between about 5 degrees and about 90 degrees relative to theprimary surface 223 of the base 221, as will be described below. Onceoriented as such, the sample end 230 may protrude out of the test stripchannel and be in close proximity to the lancet station 222 so that theuser may not have to move his/her lanced finger much and quickly measurea biological property.

Continuing with the exemplary embodiment of FIG. 6 , internal details ofan exemplary test strip channel 226 is illustrated. The test stripchannel 226 can be elongate in shape and disposed about a channel axis238 parallel to the testing module axis 236. Further, the test stripchannel 226 can terminate in the sample cavity 242 proximate to thesample end 230 of the biological test strip 228. As mentioned earlier,the sample end 230 of the biological test strip 228 can protrude out ofthe sample cavity 242 at an angle suitable for ease of access afterlancing.

Referring again to the structural features of a representative teststrip channel 226 illustrated in FIG. 6 , each test strip channelincludes a main channel portion 246 and an angled channel portion 248.In the illustrated embodiments, the test strip channel 226 can orient abiological test strip 228 such that the meter connecting end 232 can beproximate to the main channel portion 246 and the sample end 230 can beproximate to the angled channel portion 248. For instance, the meterconnecting end 232 can extend out of the main channel portion 246 andthe sample end 230 can extend out of the angled channel portion 248. Themain channel portion 246 can be generally parallel to the primarysurface 223 of the base 221 that extends in base plane B. Further, asseen in FIG. 6 , the angled channel portion 248 can form an angle withthe main channel portion 246 that equals the angle 234 formed by thesample end 230 of the biological test strip 228. Appreciably, the anglebetween the angled portion and the testing module axis 236 can alsoequal between about 5 degrees and about 90 degrees. In the illustratedembodiment, the angled channel portion 248 forms an angle of betweenabout 5 degrees and about 90 degrees with the main channel portion 246.In some embodiments, the angle formed by the main channel portion 246and the angled channel portion 248 can be between 5 degrees and 45degrees. Angles can be selected based on the depth of the sample cavity,the diameter of the sample cavity, the length of the biological teststrip, and a variety of other factors.

FIG. 8C illustrates an example test strip channel 226. The test stripchannel 226 can include a main channel portion 246 and an angled channelportion 248. A biological test strip 228 can be housed in the test stripchannel 226. As shown, the biological test strip 228 can be oriented sothat a meter connecting end 232 is proximate to the main channel portion246 and a sample end 230 is proximate to the angled channel portion. Thetest strip channel 226 can include a side walls 229A, a base wall 229B,and a bar 229C. The bar 229C can be connected to the side walls 229Aproximate to where the angled channel portion 248 forms an angle withthe main channel portion 246. In this way, the bar 229C can beconfigured to conform the biological test strip 228 housed in the teststrip channel 226 to the angle formed by the main channel portion 246and the angled channel portion 248.

In certain exemplary embodiments, the biological test strip 228positioned in the test strip channel may generally follow the contoursof the test strip channel. In such examples, the biological test strip228 can be generally flexible relative to the base 221. For instance,the meter connecting end 232 of the biological test strip 228 protrudesout of the main channel portion 246, and can be generally parallel tothe primary surface 223 of th226e base 221 (and in turn, to the testingmodule axis 236 of the testing module 220). Further, the biological teststrip 228 can be angled to match the angle of the angled portion of thetesting channel. Accordingly, the sample end 230 of the biological teststrip 228 protrudes out of the angled portion, and can be oriented at anangle of about 5 degrees and about 90 degrees with respect to theprimary surface 223 (and in turn, the testing module axis 236, as wellas the meter connecting end 232). Such embodiments permit housing 212and orienting a biological test strip 228 to facilitate ease ofmeasuring a biological property. The user can more readily access thesample end 230 because of the angled orientation, than, for instance, ifthe sample end 230 were flush with the primary surface 223 of the base221 (or were parallel thereto).

Continuing with the exemplary embodiment illustrated in FIG. 6 , thetest strip channels 226 can be of a “universal size” with dimensionssufficient to house biological test strips having a wide range of sizes.Commercially available biological test strips can be generallyrectangular in shape having a length of between about 25 millimeters andabout 35 millimeters, and width of between about 4 millimeters and about7 millimeters. The test strip channels 226 can be sized to accommodatesuch commercially available biological test strips. For instance, insome examples, the main channel portion 246 of the test strip channel226 has a length of between about 15 millimeters and about 24millimeters, and the angled channel portion 248 of the test stripchannel 226 has a length of between about 4 millimeters and about 7millimeters. The main channel portion 246 and the angled channel portion248 of the test strip channel have a common width of between about 5millimeters and about 9 millimeters. More generally, in some exemplaryembodiments, each test strip channel 226 can have a length that isbetween about 55% and about 70% of the length of the biological teststrip 228, and generally have a width approximately equal to the widthof the biological test strip 228.

Referring again to FIG. 6 , exemplary embodiments can include componentsfor sealing certain portions of the testing module 220 prior to use. Insome examples, the biological property testing apparatus 200 comprises acover tab 250 coupled to the base 221 and movable from a coveredposition to an uncovered position (e.g., using a hinged connection).With reference to FIG. 4 , all three cover tabs 250A, 250B, 250C areshown in the uncovered position. The cover tabs can be configured tocover and uncover the lancet stations, an alcohol swab section, the testsection, and other suitable components of the testing module.

Referring back to FIGS. 4 and 5 , each cover tab 250 can have acorresponding moisture barrier that can seal off a corresponding samplecavity 242. For instance, a first moisture barrier 252A can seal off thefirst sample cavity 242A when the first cover tab 250A is in the coveredposition, while the first moisture barrier 252A may not seal off thefirst sample cavity 242A when the first cover tab 250A is in theuncovered position. Similarly, a second moisture barrier 252B can becoupled to the second cover tab 250B for sealing off the second samplecavity 242B when the second cover tab 250B is in its covered position.The second moisture barrier 252B may not seal off the second samplecavity 242B when the second cover tab 250B is in its uncovered position.Further, a third moisture barrier 252C can be coupled to the third covertab 250C for sealing off the third sample cavity 242C (best seen in FIG.8A) when the third cover tab 250C is in its covered position. The thirdmoisture barrier 252C may not seal off the third sample cavity 242C whenthe third cover tab 250C is in its uncovered position

The moisture barriers permit maintaining areas surrounding test stripchannel 226 to be flushed with dry nitrogen prior to sealing with thecover tab 250. The flexible cover tab 250 provides a secondary cover tothe lancet cover 227. Further, in some embodiments, a sealant 253 can beprovided in a main channel portion 246 of the test strip channel. Thesealant 253 can further reduce, or prevent moisture from reaching thesample cavity 242 through the main channel portion 246. Appreciably,such embodiments can reduce moisture intrusion into the sample cavity242 and/or the biological test strips thereby providing for a steriletesting module 220.

Referring again to FIG. 5 , the cover tab can include a sterile barrierfor sealing off the lancet apertures. For instance, a first sterilebarrier 254A can be coupled to the first cover tab 250A for sealing offthe first lancet aperture 256A when the first cover tab 250A is in thecovered position. The first sterile barrier 254A may not seal off thefirst lancet aperture 256A when the first cover tab 250A is in theuncovered position. Similarly, a second sterile barrier 254B coupled tothe second cover tab 250B for sealing off the second lancet aperture256B when the second cover tab 250B is in its covered position. Thesecond sterile barrier 254B may not seal off the second lancet aperture256B when the second cover tab 250B is in its uncovered position.Further, a third sterile barrier 254C can be coupled to the third covertab 250 for sealing off the third lancet aperture 256C when the thirdcover tab 250 is in its covered position. The third sterile barrier 254Cmay not seal off the third lancet aperture 256C when the third cover tab250 is in its uncovered position.

As indicated previously, in some exemplary embodiments best illustratedin FIG. 6 , a hinge 258 facilitates movement of the cover tab 250between its covered and uncovered position. The cover tab 250 can befurther movable (e.g., using the hinge 258) to a re-covered position inwhich the cover tab 250 covers the sample cavity 242 and the lancet 224aperture after use. Such a re-covered position can reduce the incidenceof inadvertent lancing and of accidentally contacting the testedbiological sample. Optionally, each of the test sections can includedesiccant 251 (e.g., silica gel) in a corresponding sample cavity 242 toreduce negative effects of moisture intrusion into the sample cavity242. Such embodiments provide a sterile testing module 220 that reducesmoisture intrusion, as well as keep the testing module 220 clean andfree of microorganisms. Such embodiments improve accuracy of testresults as a result of sterile and moisture-tight packaging of thetesting module 220.

Further, some example embodiments can provide users with the ability tosterilize their finger, thumb or another portion of their body prior totesting. In one example, shown in FIG. 4 , the base 221 includes analcohol swab section 260 that may support one or more alcohol swabs.

As shown in FIGS. 9-11 , embodiments can include a biological propertytesting device 10 according to another embodiment. The embodimentillustrated in FIGS. 9-11 share many similarities with the embodimentillustrated in FIGS. 1-8C. In many cases, the biological propertytesting device 10 can be removably attached to a mobile device. Thebiological property testing device 10 can include a testing module 30and a meter module 40. The testing module 30 can include one or moretest strip stations 50. Each test strip station 50 can be surrounded bya cavity or well and can include a biological strip 60. Biologicalstrips 60 can be stabilized at an angle (e.g., 5-90°) to testing module30 (see FIG. 9 ). The preferred angle of biological strips 60 to testingmodule 30 can be about 90 degrees, though angles below or slightly above90 degrees are contemplated. In some embodiments, testing module 30 caninclude one or more lancet stations 70. Each lancet station 70 can bebuilt into testing module 30 or removably inserted into testing module30. Each lancet station 70 can include an enclosed lancet. The metermodule 40 may have measuring equipment configured to measure a propertyof a biological sample (e.g., a blood sample). The meter module 40 caninclude one or more meter sockets 80 that can each receive a biologicalstrip 60.

The testing module 30 can be connectable to the meter module 40. Themeter module 40 can include guide pins or a guide socket 90 to assist inproper alignment of the testing module 30 to the meter module 40. Whenthe testing module 30 can be attached to meter module 40, any biologicalstrips 60 contained within the test strip stations 50 are coupled withmeter module 40 through meter sockets 80 to enable communication. Whenthe test strip stations 50 and any lancet stations 70 of the testingmodule 30 have been used, the testing module 30 can be decoupled fromthe meter module 40, and a new testing module can be coupled to themeter module 40. FIG. 12 shows the testing module 30 being partiallydecoupled from the meter module 40, and FIG. 13 shows the testing module30 and meter module 40 as completely decoupled. The biological propertytesting device is described in greater detail in U.S. Pat. No.9,237,866, which is titled “Blood Glucose Management” and co-owned withthe present application, and which is hereby incorporated by referenceherein in its entirety. U.S. Pat. No. 8,647,357, which is titled “LancetDevice with Flexible Cover” and is likewise co-owned with the presentapplication, also provides additional detail on the biological propertytesting device and is also hereby incorporated by reference herein inits entirety.

As shown in FIG. 14 , in some embodiments, the lancet station 70 can becovered by a sterile barrier 100. In some embodiments, the lancetstation 70, sterile barrier 100, and test strip station 50 canthemselves be covered by a flexible cover 110, shown in FIGS. 15-16 .The flexible cover 110 can be peeled off of lancet station 70 and teststrip station 50, thereby removing sterile barrier 100 from lancetstation 70. The flexible cover 110 can be attached hingedly to testingmodule (e.g., via a die cut area). The flexible cover 110 provides amoisture barrier to the test strip station 50, allowing the cavity orwell surrounding test strip station 50 to be flushed with dry nitrogenprior to sealing with the flexible cover 110. The flexible cover 110provides a secondary cover to the lancet station 70 and sterile barrier100.

Referring again to FIGS. 15-16 , when biological strip 60 can be coupledto meter module 40, the measuring equipment of meter module 40 candetermine a blood glucose measurement (or other biological samplemeasurement). In certain embodiments, the meter module 40 can transmit asignal representative of the blood glucose measurement to the mobiledevice (or to a separate device) for display. The meter module 40 caninclude a wireless transmitter (e.g., a Bluetooth transmitter) that canbe configured to communicate with components in the mobile device (orother device). The meter module 40 can provide a wired connection toother devices. Again, additional detail on use of the biologicalproperty testing device 10 can be found in the above-referenced U.S.Pat. Nos. 9,237,866 and 8,647,357.

Referring to FIG. 17A-17B, a user of the biological property testingdevice 10 can use an application of mobile device to ready the metermodule 40 for testing. Upon a user telling the mobile device applicationthat he/she is connecting a new testing module 30 to the meter module40, the mobile device application sends a signal to the meter module 40.Upon receiving the signal, the meter module 40 recognizes the newavailable test sites and provides current to each test site. Upon a useropening the mobile device application where an existing testing module30 can be connected to meter module 40, the meter module 40 and themobile application confirm which test sites are available for use, ifany. If no sites are available for use, the meter module 40 signals tothe mobile device application that a new testing module 30 may be neededand the mobile device application communicates the information to theuser.

If any sites are available for use, whether in a newly attached testingmodule 30 or a previously used testing module 30, the meter module 40waits for a change in current caused by blood on one of the biologicalstrips 60. If no change in current is detected after one minute, metermodule 40 turns off the current. After the user lances his/her fingerwith a lancet station 70 or a separate lancet and applies blood to oneof the biological strips 60, the meter module 40 will detect a change incurrent. Upon detecting this change, the meter module 40 will ceaseproviding current to the other strips, calculate a reading from thebiological strip, and send the reading and location of the used testsite to the mobile device application. The meter module 40 will storethe location of the used test site in its own memory and will refrainfrom sending current to the used test site in the future. Afterconfirmation that the mobile device application received the data, themeter module 40 turns off. The mobile device application timestamps theblood glucose reading and converts it to mg/dL, and saves it to themobile device. The mobile device application is described further and ingreater detail in U.S. patent application Ser. Nos. 15/149,119,15/149,120, 15/149,121, which are each titled “Blood Glucose Management”and co-owned with the present application, and which are herebyincorporated by reference herein in their entirety.
